Checking and servicing the automatic transmission

How do you check and service the automatic trans of a 2006 nissan pathfinder. we recently bought one slightly used. It appears the transmission dip stick is not there and a cap attached to the tube by metal screw....is this standard? Are only the dealers servicing these?

The cap your reffering to is the dip stick. You need to remove the 10mm bolt that holds it in order to check/fill the trans. The trans takes Nissan J Matic fluid ONLY use of any other fluid will damage the trans and void your warranty(this is why it is bolted in). You will see it printed on the handle of the stick when you remove it. You can use the drain plug on the trans pan to drain the old fluid out and then refill it at the tube with a funnel.

These pathfinders have a major common problem and there is no technical service bulletin. Does your pathfinder have a hard (jerking)1-2 gear shift? does it have a hard shift in any other gears, when downshifting, or comming to a stop? Is your coolant a grey cooler or is your trans fluid bad? check your coolant on top of the radiator (when its cold) or in the coolant reservoir. Check your transmission fluid with the trans dip stick (with engine on). <br />

What is happening is the trans fluid cooler (on the bottom of the radiator) and radiator are cracking and trans fluid and coolant fluid are mixing together. If you catch this problem very very early it might be possible to fix it with a simple flush coolant and tanns flush and new radiator. But in most cases it requires a new transmission and new radiator and major flushing. It will probably happen to all pathfinders for these years, just depends on when. go to the dealership for check ups and check your coolant fluid, trans fluid, and shifting often to diag it quickly.

check or have someone check your neutral safety switch by putting transmission in park, turn ignition switch to start, and move gear selector lever at same time. if engine starts while doing this test you need to adjust safety switch! If you have a manual trans make sure to push clutch pedal as far as possible while turning key!

sounds like trans cooler in radiator has breached leaking coolant into trans and trans into coolant.i know for sure that nissan extended the warranty on radiator for this problem.i am not sure the mileage and time limits.but if you fall within those limits they should also warrant the trans as this would be the source of failure(collateral damage).good luck and remember the squeaky wheel gets the grease!1-800-nissan1.ecm relay would not be a contributing factor.

there will be a plug at the bottom of the transmission. pull the plug, let it drain, and replace the plug. Refill with the recommended amount of fluid out of the owners manual. Run the vehicle through the gears a few times with the car started. let it idle till the temp. comes up, then check the trans fluid level and add till full
